Can Plastic Containers Be Frozen?
The answer is: Yes, but the right material and usage method must be chosen.
It should be noted that not all plastics are suitable for freezing environments. Improperly chosen containers might become fragile, break, or leak toxic compounds at low temperatures. Therefore, before you freeze food in plastic containers, you should take into consideration the following factors:
Safety of the material: Common food-grade plastics like polyethylene (PE) and polypropylene (PP) are usually cold-safe and meant for freezing.
Container labeling: While you are choosing the containers, always check the bottom for signs such as “freezer-safe” or “food-grade”.
Container style: High-quality freezer containers usually come with tightly sealed lids to block smells from the freezer section.

- Avoiding thermal shock: Keep the container taken from the freezer and do not immediately place it in hot water for cleaning, as this would lead to cracks due to the difference in temperature.
- Seal it with a lid: Make your favorite odorous or put stuffing on top, to block its escape and accumulation of frost.
